Original publication title: Preliminary favorable outcomes of total proximal tibial osteotomy for medial patellar luxation in juvenile dogs.

Plain-English summary
A young dog with medial patellar luxation (MPL), a condition where the kneecap slips out of place, underwent a surgical procedure called total proximal tibial osteotomy to correct the problem. After the surgery, the dog's knee alignment improved, and it was able to bear weight quickly, showing no complications. By 30 days post-surgery, the dog was doing well, with no signs of the kneecap slipping again. This surgery appears to be a promising option for young dogs with this condition, helping them recover effectively and maintain proper knee alignment.

Abstract
BACKGROUND: Excessive tibial torsion contributes to medial patellar luxation (MPL) in dogs. Total proximal tibial osteotomy in juveniles is intended to correct this deformity while preserving the integrity of the growth plates. OBJECTIVE: To evaluate outcomes of juvenile dogs with MPL after total proximal tibial osteotomy. ANIMALS AND PROCEDURE: Four stifles from 3 juvenile dogs were analyzed. Retrospective cases were evaluated, focusing on stifle extensor mechanism (SEM) alignment, femoral and tibial measurements, patellar stability, and surgical complications. RESULTS: The mean external tibial torsion was 31.87° ± 10.53°. Postoperatively, SEM alignment was achieved in all cases, and tibial alignment between 0° and 5° was maintained during radiographic follow-up. No complications occurred and weight-bearing returned early, with optimal outcomes by Day 30. Patellar reluxation was not observed. Long-term follow-up revealed sustained SEM and tibial alignment after physeal line closure. CONCLUSION AND CLINICAL RELEVANCE: Total proximal tibial osteotomy shows promise for the management of MPL associated with excessive tibial torsion in juvenile dogs. This technique may offer a reliable surgical alternative to traditional methods, promoting early recovery and long-term tibial realignment in young dogs with MPL.
